1. Unified Subsidence Threshold Direction Approved The Board voted unanimously to direct staff to develop a single minimum threshold (MT) for subsidence across the entire GSA, moving away from a two-tiered concept that would have imposed stricter limits on border areas. The final MT value will be developed by staff working with the Growers Committee and consultants and then brought back to the Board for approval, with discussion indicating it could be within a range such as 4 to 7 feet from the 2020 baseline. This decision ensures all landowners face the same subsidence restrictions regardless of location, though specific actions will still be triggered at different percentage thresholds (40%, 50%, 75%, and 100% of MT). At 100% of the threshold, the GSA would stop pumping from C-zone wells contributing to subsidence in affected areas only.
